The purpose of this research is to study aerated concrete basing on thermal conductivity with orthogonal experimental method.Aerated concrete is prepared and then curved by the method of vapor curing and carbon dioxide curing.The influences of the ratio of water to ingredient and mixing quantity of raw materials on the thermal conductivity of aerated concrete are investigated.Moreover, an optimum mixing proportion is determined with orthogonal experimental method.Range analysis results show that the optimum mixing proportion is: Aluminum powder : Silica sand : Gypsum is 0.08% ∶ 45% ∶ 4%, the ratio of water to ingredient is 0.50, and the content ratio of cement and lime is 1∶ 2.Variance analysis results show that the ratio of water to ingredient and the mixing quantity of raw materials are not remarkable influencing factors.The ratio of water to ingredient also has effect on the thermal conductivity of aerated concrete.

中胡(中音二胡的简称)是重要的中国弓弦乐器之一,其形状与被称为"中国小提琴"的二胡相似.作为中国民族乐队中不可或缺的中音乐器,对其声功率级及其频谱特征的测试研究对于了解乐器辐射的声音特征无疑具有重要的意义.本文介绍了在半消声室内对中胡声功率级的测试工作.测试内容包括单音、音阶和乐曲,测试分别在pp,mp,f和ff四种演奏力度下进行,获得了中胡的代表性声功率级数据.通过与在混响室内的测试结果相对比,
随着办学方向的改变,许多高校原有校办工厂已废弃,本文以内蒙古工业大学废弃旧厂房改造而成的建筑馆为例,阐述在高校旧厂房建筑改造中室内通风设计部分充分利用原有建筑构件,诸如烟囱、地道、排风管道等,结合金属孔板、通风口、通风竖井、可开启窗等,强化室内自然通风的作用效果,使整个室内通风设计达到生态、节能、环保的目的.

根据Fanger热舒适模型和人工免疫算法在解决组合优化等问题方面的优势,将其应用于建筑热工设计和空调系统的参数优化方面.针对夏热冬暖地区的高温高湿的气候特点,建立室内热舒适目标函数,确定在不同湿度和活动状况下满足热舒适要求的室内空气温度和风速范围,进而可揭示室内热舒适与围护结构隔热之间的关系.研究表明,基于人工免疫算法的室内热舒适组合优化可以作为建筑热工设计和空调系统控制的依据.

在采暖地区建筑物的体型系数对建筑的冬季采暖能耗影响很大,体型系数是建筑节能设计的重要技术指标.目前使用的体型系数计算方法仅能反映建筑物向室外释放热能的情况,对冬季建筑物获得太阳辐射能没有考虑.本文在对冬季太阳辐射持续观测的基础上,通过对建筑的不同外表面获得太阳辐射热能的分析,提出了基于太阳能获得强度的外表面积修正系数,对现用的体型系数计算方法进行了修正.这一研究结果对在建筑设计中更好地利用冬季太阳
双层皮玻璃幕墙是一项起源于欧洲、近十年真正发展起来的新技术.近年来我国的一些建筑也开始使用这项生态建筑技术.本文对双层皮玻璃幕墙的发展过程及优缺点做了概要介绍,并分析双层皮玻璃幕墙对于不同于欧洲气候的夏热冬冷气候是否具有适应性.
舒适是室内热环境设计的基础,建筑的舒适性也就成为人们追求的目标.本文以河南理工大学土木工程学院办公楼为例,通过对其测试分析之后分析了该建筑的热环境特点,并从不同方面提住了自己的一些改造建议,以期得到舒适的建筑热环境.
